1/5 Earth Science update and homework due 1/12

Hi folks,

Today we finished up the most recent Rock Cycle and Earth Layers block by doing our favorite "Review the Year" gameshow.  The students look through their notes, homework, and quizzes from the beginning of the year up to now and create five questions for the show.  Then each team gets a chance to answer the questions for points and fabulous prizes.  (Just kidding on the prizes.)  This makes for an excellent summary of the content we've covered so far and it's quite a bit of fun.

For homework please answer all the following questions.  They cover much of the year so please look through your notes and old quizzes for the answers.  As always, these are quite possibly going to be on an upcoming quiz so be sure to study them carefully.
